Signal/Image Processing

Compressed video transmission as used in HDTV and on the
Internet requires
sophisticated signal and image processing for the storage and transmission of
images and video. Research in
this area focuses on digital signal and image
processing, with an emphasis on image and video compression,
joint source channel coding, multimedia applications, and neural networks.

Projects

For a given power constrained Gaussian communication channel, we consider
the optimum theoretical allocation
of energy per bit for a BPSK transmitter when the performance is
measured by end-to-end average quantizer distortion.
Choosing the average energy per transmitted bit in conjunction with both
the source rate and the channel code rate
provides one additional degree of freedom with respect to
previously proposed schemes for discrete channels,
and therefore achieves higher overall PSNR values for images.
